The perpetrators of the recent spate of financial frauds in the USA acted with callous disregard for both their employees and shareholders - not to mention other stakeholders. Psychologists have often remote-diagnosed them as "malignant, pathological narcissists".
Narcissists are driven by the need to uphold and maintain a false self - a concocted, grandiose, and demanding psychological construct typical of the narcissistic personality disorder. The false self is projected to the world in order to garner "narcissistic supply" - adulation, admiration, or even notoriety and infamy. Any kind of attention is usually deemed by narcissists to be preferable to obscurity.
The false self is suffused with fantasies of perfection, grandeur, brilliance, infallibility, immunity, significance, omnipotence, omnipresence, and omniscience. To be a narcissist is to be convinced of a great, inevitable personal destiny. The narcissist is preoccupied with ideal love, the construction of brilliant, revolutionary scientific theories, the composition or authoring or painting of the greatest work of art, the founding of a new school of thought, the attainment of fabulous wealth, the reshaping of a nation or a conglomerate, and so on. The narcissist never sets realistic goals to himself. He is forever preoccupied with fantasies of uniqueness, record breaking, or breathtaking achievements. His verbosity reflects this propensity.
Reality is, naturally, quite different and this gives rise to a "grandiosity gap". The demands of the false self are never satisfied by the narcissist's accomplishments, standing, wealth, clout, sexual prowess, or knowledge. The narcissist's grandiosity and sense of entitlement are equally incommensurate with his achievements.
To bridge the grandiosity gap, the malignant (pathological) narcissist resorts to shortcuts. These very often lead to fraud.
